multipart post problem

[Segal, Jeffrey]

Hello all,
 
I've been having some problems trying to use HttpClient to upload files.
My platform:
 
Client: Stand-alone Java client, httpclient: 3.0.1
Server: Weblogic 9.1, commons-fileupload 1.1.1
 
When I execute the code I attached below (trimmed a bit for space),
which appears to be correct per the tutorial, I receive the following
error:
 
"Upload failed: org.apache.commons.fileupload.FileUploadException: the
request was rejected because no multipart boundary was found"
 
If I don't manually set the Content-type or Content-length, I get
corresponding errors as well.  Strangely, if I use the deprecated
MultipartPostMethod, I do not receive the error above and the upload
works for very small files.  However, for any reasonably sized file
(>1KB), I receive the following exception on the client side:
 
java.net.SocketException: Software caused connection abort: socket write

I'm completely at a loss here...any ideas?
 
Thanks,
